  Purpose

The purpose of the study is to determine the maximal tolerated dose and schedule of CC-486 (also known as oral Azacitidine) in patients with AML or MDS after allogeneic HSCT. Allogeneic hematopoietic stem cell transplantation (HSCT) is more frequently used in Acute Myloid leukemia (AML) or Myelodysplastic Syndromes (MDS) as a potential curative therapy. However, disease recurrence/relapse and graft-versus-host disease (GVHD) remain the principal causes of fatal complications after transplantation. Azacitidine has significant activity in MDS and AML. Azacitidine has also demonstrated immunomodulatory activity in AML patients after allogeneic HSCT. An oral formulation of Azacitidine provides a convenient route of administration and an opportunity to deliver the drug over a prolonged schedule.

Study Start Date: July 2013
Estimated Study Completion Date: September 2016
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Oral Azacitidine
Dose of 200 or 300 mg once daily (QD) for the first 7 or 14 days of each 28-day cycle, starting 42-84 days after transplantation.
Drug: Oral Azacitidine
Dose and schedule finding within the first 2 cycles (Cycle 1 and 2). Cohort 1: 200 mg QD, Days 1 to 7; Cohort 2: 300 mg QD, Days 1 to 7; Cohort 3: 200 mg QD, Days 1 to 14; Cohort 4: 300 mg QD, Days 1 to 14. Cohort 1 will be evaluated first. If the dosing regimen is confirmed to be safe in Cohort 1, other cohorts will be evaluated sequentially based on a standard "3+3" escalation scheme.

Detailed Description:

This is an open-label, multicenter study of oral Azacitidine in MDS or AML patients who have undergone allogeneic HSCT. The study consists of three phases: Screening, Treatment and Follow-up. During the Screening phase, which will take place within 4 weeks before starting oral Azacitidine, the study doctor will do tests to see if the patient is suitable for this study. The patient meeting protocol-specified entry criteria will enter the Treatment phase and be assigned to receive oral Azacitidine at 200 or 300 mg once daily (QD) for the first 7 or 14 days of each 28-day cycle. The dosing group of 200 mg QD on Days 1 to 7 will be evaluated first (ie, Cohort 1). In the event that unacceptable toxicity occurs in Cohort 1, then oral Azacitidine may be evaluated at lower dose levels (eg, 150 mg). If the dosing regimen is confirmed to be safe in Cohort 1, other cohorts will be evaluated sequentially. During the treatment phase, subjects will be monitored closely for safety and tolerability. Dosing interruption or delay, dose or schedule reduction, intra-subject dose/schedule escalation or re-escalation may occur on the basis of protocol-specified dosing adjustment guidelines. Safety will be monitored throughout the study at predetermined intervals and as clinically indicated by vital signs, physical examination, performance status, laboratory tests and evaluation of adverse events. The patient can continue to receive the study treatment for up to 12 months provided that they benefit from the study treatment and all protocol-specified criteria are met. However, the patient may receive the study treatment for less than 12 months due to adverse event, disease recurrence or progression. When the study treatment is discontinued, all patients who have received at least one dose of oral Azacitidine will be asked to see the study doctor for the Treatment Discontinuation visit. Thereafter, all patients discontinued from the study treatment will enter the Follow-up phase for safety and survival follow up.
